Yo Need Help, I Got A 03 Coupe.. So Its A Non Rev Up.. N I Want The Mrev2 Wit The Spacers...need Tuning/? Or.....

 

since you have a non-revup engine, a 5/16" spacer alone will suffice. the addition of the mrev2 will cause you to run lean until you get a tune.

 

^^^ yea thats true but with mrev2 and a spacer youll hear and feel the difference

 

so u think i should get that mod for my non rev up?

 

Pick one or the other for a nonrevup engine. The MREV2 makes slightly more power than the spacer according to Tony at motordyne.

 

I don't think the mrev on a none-rev up makes enough diff to cause a lean condition. Especially when Tony himself said it's worth only about 2-3 hp on a non-rev up.

So I'd just get the 5/16" spacer.

 

how much does the spacer go for?

 

Um. If you know about the 5/16" spacer, then you know who makes them and therefore know where to go to find pricing. Or hit the classifieds and try to find one used

 

Its actually 4-6 more HP when used with a spacer.

The MREV2 by itself makes good power. Below is a plot generated by Wired24/7. He's one of the forum moderators over at My350z.com.

He did a full dyno test and write up on the Z forum a while back.
This was done on a non revup engine.
